XPO1-mediated TRIM21 nuclear export reprograms TREM2+ macrophage polarization by targeting IRF3 to augment anti-PD-1 efficacy in small cell lung cancer
Small cell lung cancer (SCLC) is an aggressive malignancy that responds poorly to immune checkpoint inhibitor (ICI) therapy, due to its immunosuppressive tumor microenvironment. Here, we analyse preclinical mouse tumor models and patient-derived SCLC samples and identify Exportin 1 (XPO1) as a regulator of immune suppr...
